Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI NAT Gateway.
Why it's wrong here
A NAT Gateway allows private resources to initiate outbound connections to the internet, but does not provide secure inbound administrative access.

Why it's wrong here
A Load Balancer distributes incoming application traffic, not secure administrative terminal access.

Why it's wrong here
API Gateway is designed to publish, secure, and route REST APIs, not provide SSH terminal access to compute nodes.

Why this is correct
